sh-pfc: r8a7778: add VIN pin groups 



Add VIN DATA[0:8]/CLK/HSYNC/VSYNC pin groups to R8A7778 PFC driver.
While at it, add SH_PFC_MUX8() macro for 8-bit data busses.

[Sergei: updated the copyrights, added SH_PFC_MUX8() macro for 8-bit data bus,
made use of SH_PFC_*() macros to define the pin groups.]
